ok im a lil confused. do i need to flash the bios to asus or MSI on my HIS5870 to be able to change the voltage?
If you figure that one out let us know. I had a non-reference fan model (xfx) that I was able to bump up the voltage slightly. And I mean only slightly (up to 1.163), but It gave me the ability to go over 1020 core.
I tried the MSI BIOS which with my card, didn't work with afterburner. Go figure Msi after burner didn't work with MSI Bios...humm. With asus bios, i was able to over volt with the asus doctor software.
It's fairly easy to flash the bios back and forth, so I'd give it a try if I were you.
